$40,000 Speakers Make You Feel Like Marty McFly in Back to the Future

These substantial looking speakers are the Mark Neumann Coliseum XLS and they’ll blow your socks off, just like Marty McFly in Back to the Future. If you have any question about how beefy they are, the pair has a shipping weight of 580 pounds!

With open-baffle acoustics inspired by a concert grand piano, these speakers are designed to disperse sound 360 degrees. They are made out wood, measure 43¾ inches in height, 18 inches in depth, and have a depth of 22 inches. Inside, they each have two 7-inch E7 reference drivers, a pair of high-frequency tweeters and the bass system has two 8-inch woofers.

With an average sensitivity of 95 dB and full-range frequency response from 20 Hz – 20kHz, they must sound great with recorded music. Still, nothing beats having ginormous speakers plugged into a guitar. Needless to say that your neighbors will hate you.

If you’ve got an extra $40,000 lying around, then you’d better act fast because these speakers are truly limited – with just 12 pairs being produced.
